Replacement/upgraded lid for Calway vibrating rock tumbler.

My mom asked me to design a replacement lid for her vibrating rock tumbler, and this is what I came up with. has threading to get a tighter seal, and to lock it in place better, and hook points for running a small bungee cord to hold it in place. After searching, I realized these things are severely lacked. with the only other 3d printed Calway vibrating tumbler lid I've seen being on a youtube video, from someone who absolutely refuses to link to the file, share their file, offer service, or even mention who made the damn thing. Note: Print settings and material are just what "I" used. none of this is set in stone.
